I've been running into issues where games will usually run poorly on setting that used to work without any lag. I have the GT 650M and have been trying to playing Skyrim. and it ran well at first, but has been lagging even though I've gone as far as to set the graphics to low quality. I play with the laptop plugged in and give it room to vent, and I've updated the drivers. Anyone have any idea how to fix this?
